The paper describes a methodology of verifying that coiled tubing strings have not been subject to erosion caused by annular fracturing operations.
In previous features, the focus has been on what is new or reimagined. Therefore, I thought that, in selecting papers for this year’s feature, it would be useful to select ones that look at coiled tubing operations performed and that have been evaluated in one way or another.
The paper describes the iterative process of development of a novel shear blade able to cut high-strength coiled tubing with 50% of the normal shear force.
